ISAAC HNMILLIKEN, OF ASPINWALL, PENNSYLVANIA, ASSIGNOR TO THE MCCONWAY & TORLEY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

To all whom it may concern:

Be it known that I, ISAAC H. MILLIKEN, a citizen of the United States, residing at Aspinwall, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wear-Plates for Car-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the construction of wear plates for protecting a car coupler from wear due to rubbing back-and forth over the surface of the carry-iron by which it is supported at the end of the car. primary object of the invention is to provide a device of the character indicatedably connect the forward end of'the plate to the coupler in a manner preventing longitudinal and lateral shifting of said plate relatively to the coupler.

In the drawings illustrating my invention, the scope whereof is pointed out in the claims,

Figure 1 is an inverted plan view of a device embodying the invention.

Fig. 2 is a side elevation of the construction illustrated in Fig. 1.

Fig. 3 is an inverted plan view of another embodiment of my invention.

Fig. 4 is a side elevation partly in section of the construction illustrated in Fig. 3, a supporting carry-iron being also shown.

Fig. 5 is an inverted plan view of another modification of the invention.

Fig. 6 is a side view of the form of the device shown in Fig. 5.

Fig. 7 is a detail view corresponding to Fig. 5, but illustrating a still further modification of my invention.

In the drawings, 1 indicates the head of a car coupler and 2 is its stem. A carry-iron 4 for slid-ably supporting thecoupler is illustrated in Fig. 4, while a yoke 5, of well The WEAR-PLATE FOR CAR-COUPLINGS.

I known form, serving to operatively connect the coupler to the cushioning elements of the draft rigging is shown in Figs. 3 and l. Except as otherwise defined by the claims these parts or their equivalents may be of any desired form.

- The wear plate (3 illustrated in Figs. 1 and 2 is provided at its rear end with a pair of spaced upwardly extending lugs 7 between which the stem 2 of the coupler is closely embraced, the rear end of the plate 6 being thereby restrained from lateral movement.

The forward end of the wear plate is detachably secured in position beneath the coupler by means of a removable bolt 8 which, as shown, may be employed if desired as a pivot pin for pivotally connecting the coupler head 1 to the stem 2. The pin 8 prevents longitudinal movement of the plate and prevents lateral shifting of its forward end.

In the construction shown in Figs. 3 and 4 the pin 9 for detachably connecting the front end of the wear plate 10 to the coupler is rigidly secured to the plate and extends upwardly therefrom into a corresponding'hole or recess 11 formed in the coupler. When the coupler head is not pivotally connected to the coupler stem this form of construction is preferred for connecting the forward end of the wear plate to the coupler. At its rear end the plate 10 is preferably provided with spaced upwardly extending lugs 12 which overlap the sides of the coupler stem 2 and thus restrain lateral movement of this end of the plate. While the pin 9 operates to prevent longitudinal movement of the plate 10 in both directions, the plate may, if desired, extend rearwardly far enough to abut the forward end of the draft yoke 5, the yoke in'such case serving to prevent rearward shifting of the wearplate. I

The construction illustrated in Figs. 5 and 6 is an embodiment of my invention wherein the pin or bolt 13 for securing the front. end of the wear plate 14 to the coupler is employed to also attach the coupler unlocking mechanism to the coupler. In the specific form of construction illustrated in these views the wear plate 14 is provided at its forward end with a laterally extending perforated arm 15 whose perforation is adapted to register with similar perforations in pivot lugs 16 formed on the bottom of the iii) coupler adjacent the knuckle side thereof to receive a coupler unlocking lever 17 between them.

The wear plate 18 illustrated in Fig. 7 also is attached at its forward end to the coupler through the instrumentality of a bolt or pin 19 serving to pivotally connect the coupler unlocking lever 20 to the coupler. For this purpose the plate 18 may be provided at its forward end with a pair of perforated lugs 2i which fit closely against the outer faces of a correspondingly perforated. pair of lugs 22 projecting downwardly from the coupler substantially at the junction of the head 1 and stemQ. The bolt 19 passing through the lugs 21 and 22 sustains the forward end of the wear plate 18 in assembled relation with the coupler. The rear ends of the plates let and 18 are preferably provided with spaced upwardly extending lugs corresponding in form and function to the lugs 12 at the rear end of the plate 10, as shown in Figs. 3 and 4.

I claim:

1. In a device of the character indicated,

the combination with a coupler head and stem of a wear plate associated therewith, said wear plate located beneath and in contact with the stem, said wear plate )rovided at its rear end with a plu 'ality o spaced lugs adapted to embrace the lateral walls of the coupler stem and restrain lateral movement of the wear plate on the stem, and a pin for connecting the wear plate and conpler head and preventing longitudinal movement of the wear plate with respect to the coupler head and stem.

2. In a device otthe character indicated,

the combination with aicar coupler, of a wear plate associated therewith and ar' ranged beneath the same, said parts having interlitting engagement preventing lateral movement of the rear end of the plate with respect tothe coupler stem, and a detachable pin pivotally connecting the head of the coupler to the stem thereof and securing the forward end of said plate to the coupler.

- In testimony whereof I aflix my signature.

ISAAC H. MILLIKEN.
